IMPROVEMENT IN SIPHONS.

Specication forming part of Letters Patent No. 201,746, dated March 26,1878; application filed February 20, 1878.

To all whom it may concern: i

Be it known that I, EMILIO GAEDARELLI, of Washington city, in theDistrict of Columbia, have invented certain new and useful Improvementsin Siphons; andIdo hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference beinghadto the accompanying drawing, and to letters of reference marked thereon,which form a part of this specification.

My invention relates to siphons used for drawing various liquids fromcasks and other vessels, the object of the invention being to producei asiphon which is readilyT adjusted and put in operation, and the liquidto be drawn .is quickly started and caused to run through the siphon.

The accompanying drawing represents a siphon with my improvementsapplied thereto.

In my construction a siphon of ordinary form has an air-pump attachedthereto at or near its outer or discharge end, havingcommunication withthe siphon for the purpose of exhausting the air from it, so that theliquid is caused to ilow through the siphon.

The suctiontubel of the pump is constructed of such size as to containjust the quantity of air held by or contained in the tubeformin g thesiphon, .so that by a single upward stroke or draft of the rod holdingthe plunger the air is exhausted from the siphon and drawn into thesuction-tube, and the liquid to be drawn immediately commences to flowthrough the siphon without entering the air-exhausting pump.

A suitable stopper is provided for the end of the siphon from which theliquid is discharged, so that the outlet is readily opened or closed.The siphon has also an air-vent, which is: kept closed during thedrawing of liquid, and is opened when it is desired to stop the iow.

A designates the main tube forming the si phon, the end ofthe tube whichis placed in the liquid to be drawn being marked c, and the end fromwhich the liquid is discharged being indicated by b.

B is the suction-tube of the airpump, se-

cured to the siphon at or near the discharge l end b, and within whichtube B is the rod c, holding the plunger.

C indicates the communication between the suction-tube B and thesiphon,and D the stopping or closing apparatus, having the rod andhandle d for opening and closing thedischarge end b.

E is the air-vent, with suitable means for opening and closing the same,the vent being opened when it is desired to stop the flow of liquidthrough the siphon.

The brace F serves to strengthen and support the siphon.

When the siphon is placed in position for drawing liquid from a tank orother vessel, the plunger-rod c is drawn upward as far as theconstruction of tube B will permit, and as the tube B will hold just thequantity of air. that is contained in tube A, the latter becomesimmediately exhausted of air, the same having passed through tube C intothe tube B. The tube A being filled, the stopper D is pushed downward,and the discharge end of the siphon is opened, so that the liquid passesout and continues to flow through the tube A until stopped by openingthe vent E.

Having described my invention, I claim- In combination with the longerleg of a siphon, the air-exhausting pump B c and stopper D, having theguided operatingrod d, substantially as set forth.

In 'testimony that I claim the foregoing as my own I have afxed mysignature in presence of two Witnesses.

EMILIO OARDARELLI.
